Abstract:V letu 2014 je bil na posestvu Fakultete za kmetijstvo in biosistemske vede, Univerze v Mariboru, izveden poskus v nasadu jablan sorte Fuji. Ugotavljali smo učinkovitost najpogosteje uporabljenih fitofarmacevtskih sredstev za zatiranje krvave uši, ustreznost izbranega časovnega termina za zatiranje krvave uši in vpliv fitofarmacevtskih sredstev na parazitizem krvavih uši. Poskus je bil zasnovan v naključnem blok sistemu s štirimi ponovitvami. Pozimi, spomladi in poleti so bile izvedene aplikacije v štirih različnih terminih pri porabi 700 l/ha škropilne brozge. Rezultati kažejo, da je bila največja učinkovitost insekticidov dosežena v januarskem terminu s pripravki Pirimor (82,34%), NeemAzal (72,94%), Karate (66,19%) in Pyrinex (64,02%). Po drugem terminu škropljenja se je učinkovitost pri vseh pripravkih bistveno zmanjšala predvsem zaradi višjih temperatur od običajnih. Ekološki škropilni program zatiranja krvave uši je bil najmanj učinkovit. Največji parazitizem uši je bil dosežen pri prvem terminu škropljenja, ko je bil parazitizem uši v povprečju 10,64%. V integriranih škropilnih programih še vedno dosegamo dobre rezultate zatiranja krvave uši s pripravkom Pirimor, saj ima višjo učinkovitost kot ostala sredstva in najmanj vpliva na parazitizem s strani krvavkinega najezdnika.

Title:Control of Wooly apple aphid (Eriosoma lanigerum Hausmann) in apple orchards
Abstract:In the year 2014, on the Faculty of the agriculture and applied sciences’, University of Maribor property an experiment in Fuji apple orchard was conducted. We examined the effectiveness of the mostly used pesticides for control of wooly apple aphid, adequacy of selected time period for control of wooly apple aphid and impact of pesticides on parasitism of wooly apple aphids. The experiment was organized in random block system with four repetitions. In winter, spring and summer the applications of different insecticides in form of 700 l/ha spray mixture were performed. Results show that the greatest effectiveness of insecticides was accomplished in January term with preparations Pirimor (82,34%), NeemAzal (72,94%), Karate (66,19%) in Pyrinex (64,02%). After the second term of treatment the effectiveness of all the preparations was significantly reduced due to the higher temperatures in comparison to the first treatment. Ecological spray programme for control of wooly apple aphid was at least effective. The highest parasitism of wooly apple aphid was reached in first term of treatment, where the parasitism was 10,64 % in average. In integrated spray programmes we can still expect good results of the control of wooly apple aphid by using Pirimor preparation, while it has higher effectiveness in comparison to other preparations and has the lowest impact on the parasitism from parasitoid wasp.
